Code folding is a feature of some text editors and IDEs that allow some text to be temporarily hidden or "collapsed" in order to hide detail.
Most text editors and IDEs offer some way of hiding sections of the code in order to traverse the code more easily, only view the code currently being edited, and to show an outline of what code currently is in the file.
What code counts as a section and hence can be hidden, can be user specified or automatically added based on the syntax of the language, indentation or tokens (such as brackets).
